“…3 Many activation methods involve the use of abundant Sn catalysts, the most efficient being Sn-zeolites. [10][11][12][13][14][15][16][17] Other metals used for the activation of hydrogen peroxide in the BV oxidation include Se, 18 Re, 19 Li and Ca borates, 20 Pt, [21][22][23] Pd, 24 Si polyoxometalates, 25 and Zr. 26 Metal-free methods also exist and make use of enzymes, 27 ionic liquids, 28 carboxylic acids, 29 phosphoric acids, 30,31 and bisflavins 32 to activate the peroxide.…”
